How can I append a number at the end of a string object?
Author
So far I've got this
u32 attachedControlers = getNumberOfControls();
//vector to hold player names
vector<string> names;
if (attachedControlers > 1 && multiPlayer(attachedControlers))
for (int i = 0; i < attachedControlers; ++ i) {
names.push_back("Player");
}
else names.push_back("Player1");
But what I need is something that adds a number to the end based on what i is equal too, so if attachedControlers == 3 I will fill my vector with "Player1", "Player2" and "Player3", but I don't know how to append a number to the end without using c style strings.
With std::stringstream:
// #include <sstream> at the top of your filestd::stringstream str;str << "Player" << attachedControlers;names.push_back(str.str());
You can use std::ostringstream.
also to make it a little more readable, and if you are not afraid of using boost, you could write

std::string Playername = "Player";std::ostringstream StrStream;StrStream << i;Playername.append( StrStream.str() );also to make it a little more readable, and if you are not afraid of using boost, you could write
std::string Playername = "Player";Playername += boost::lexical_cast< std::string > ( i );best Jochen

boost is a well known and imho very usefull resource for C++ developers.
You can find out about boost at www.boost.org.
boost::lexical_cast is a library that's part of boost.
